Mathematical open problems in Projected Entangled Pair States [article]

J. Ignacio Cirac, José Garre-Rubio, David Pérez-García
2019 arXiv   pre-print
The aim of this paper is to present, for a broad mathematical audience, some mathematical questions about PEPS.  ...  Projected Entangled Pair States (PEPS) are used in practice as an efficient parametrization of the set of ground states of quantum many body systems.  ...  However in 2D the analogue problems are quite open. First of all, there is no known solution of the local approximation problem.  ...

Five open problems in compressible mathematical fluid dynamics

Denis Serre
2013 Methods and Applications of Analysis  
The problems below are motivated by some of the works I did in the past. They deal with the dynamics of compressible fluids, either viscous or inviscid.  ...  They are not worth a million dollars, even not a penny, but they are interesting in their own.  ...  The open problems are countless, and our choice of five of them is strongly biased by our own mathematical interest and previous research.  ...

The Discrete Logarithm Problem [chapter]

René Schoof
2016 Open Problems in Mathematics  
In this expository paper we discuss several generalizations of the discrete logarithm problem and we describe various algorithms to compute discrete logarithms.  ...  For large prime numbers p, computing discrete logarithms of elements of the multiplicative group (Z/pZ) * is at present a very difficult problem.  ...  Exponential algorithms Following ideas in [11, section 7] , we consider the following general problem. It is a natural extension of the discrete logarithm problem. Problem.  ...

Using open problems and cooperative methods in mathematics education

András Ambrus, Krisztina Barczi-Veres
2015 LUMAT  
Two aspects are taken into consideration in connection with mathematical problem solving: open problems and cooperative teaching.  ...  Roughly speaking we can differentiate between two main styles in teaching mathematics: either the focus is on the students or the focus is on mathematics as a science.  ...  In our experiment opening problems goes in this direction 2.  ...
